After a relatively cool spring, the D.C. area is going to get a blast of mid-summer temperatures this weekend, and forecasters want residents to prepare.

The National Weather Service has issued a Special Weather Statement for D.C., Arlington and the region, cautioning about “early season heat” that could cause heat illness “unless proper precautions are taken.”

The mercury is expected to rise above 90 degrees over the next three days, including an expected high temperature of 95 on Saturday, which would tie the record from 1934.

The full statement from NWS is below.

203 PM EDT Thu May 19 2022

…EARLY SEASON HEAT FRIDAY THROUGH SUNDAY…

Temperatures will rise into the 90s Friday, Saturday, and Sunday for the first time since last Autumn. Friday will be the first 90 degree day in the Baltimore and Washington Metropolitan Areas since last September. Saturday is forecast to be the hottest day of the weekend, with many locations reaching the mid-90s and heat indices approaching 100. This level of heat will continue through Sunday.

The abrupt beginning of hot temperatures early in the season after a relatively cool spring brings an increased risk of heat illnesses unless proper precautions are taken for those working or recreating outdoors.

Since many outdoor events are planned this weekend in the region, be aware of the heat, and take extra precautions if you work or spend time outside this weekend. Reschedule strenuous activities to early morning or evening. Plan to wear lightweight and loose fitting clothing, and seek shade from the sun. Schedule frequent… breaks in shaded or air conditioned environments and stay hydrated with non-alcoholic beverages.

The advisory, which goes into effect at midnight and is set to lift at 9 a.m., advises residents to “take steps now to protect tender plants from the cold.”

It’s going to be a foggy night.

Arlington and much of the region is now under a Dense Fog Advisory. The advisory is in effect until 10 a.m. Friday.

Update at 3 p.m. — Snow is starting to taper off. Roads are mostly clear, after just over an inch of snow fell on Arlington.

Update at 9 a.m. — Snow continues to fall amid strong winds, reducing visibility and causing slick conditions on some paved surfaces. All lanes of westbound I-66 are currently closed at Spout Run due to a crash. It’s unclear whether the crash is weather related.

Earlier: Frozen precipitation is now falling on Arlington and forecasters warn that things are going to get a lot worse before they get better.

Rain is changing over to snow as temperatures fall and strong wind gusts whip up, thanks to a strong cold front and storm system making its way up the East Coast.

In addition to the earlier Winter Weather Advisory and Wind Advisory, the National Weather Service this morning issued a Special Weather Statement urging extra caution on the road if you absolutely must travel during the “near blizzard conditions” expected later this morning.

646 AM EST Sat Mar 12 2022

…RAPIDLY DETERIORATING CONDITIONS THIS MORNING…

Rain will change to snow over the Washington and Baltimore Metropolitan areas as well as northeastern Maryland by 9 AM this morning from northwest to southeast. Snowfall rates around one to two inches per hour are expected through late this morning along with rapidly falling temperatures below freezing. Despite the recent warm conditions, snow is expected to stick on many surfaces, causing travel disruptions.

Strong northwest winds with gusts around 45 to 55 mph are expected during this time, causing snow and possible blowing snow to reduce visibility below one-half mile at times. Near blizzard conditions are expected.

Please use extra caution if you have to travel.

Get ready for a wintry and windy Saturday.

A Winter Weather Advisory and Wind Advisory, both of which take effect Saturday morning, were just issued for Arlington. Forecasters expect wind gusts up to 55 mph and snow accumulation of 2-4 inches as a storm system moves up the East Coast.

Also from NWS:

326 PM EST Fri Mar 11 2022

…WIND ADVISORY IN EFFECT FROM 6 AM SATURDAY TO 1 AM EST SUNDAY…

* WHAT…Northwest winds 25 to 35 mph with gusts up to 55 mph.

The Washington Post’s Capital Weather Gang is a bit more measured in terms of its snow accumulation prediction for Arlington, calling for a coating to 2-3 inches of snow accumulation, with higher amounts north and west.

The storm is expected to start as rain before changing over to snow mid-morning. In such scenarios, snows crews typically do not pre-treat roadways as the treatment would be washed away by the time the frozen precipitation starts.

VDOT said Friday afternoon that its plow crews are ready to tackle the snowy onslaught, while asking drivers to stay at home if at all possible.

VDOT Northern Virginia crews are ready for winter weather that is forecast to impact the region Saturday. The forecast shows precipitation starting as rain and turning to snow. Residents should be ready for high wind gusts and below freezing temperatures.

As always, residents are asked to monitor forecasts and plan ahead to avoid nonessential travel during winter weather.

What’s Happening Now

  • See the Winter Weather Advisory from the National Weather Service for precipitation for Saturday. The forecast includes periods of rain and accumulating snow, as well as increased winds. Please continue to monitor forecasts closely as forecasts can improve or worsen quickly.
  • Crews will mobilize overnight to treat state-maintained roads. Please drive with caution around plow trucks as they are heavy and move slowly.
  • Temperatures are expected to drop below freezing, causing potential icy conditions. Treat anything that looks wet as if it could be icy, especially bridges, ramps, overpasses, and elevated surfaces. If there is snow or ice on roadways, travel is hazardous.
